# Download and install patchelf v0.18.0 from GitHub. The default Ubuntu focal
# packages only provide the "0.10-2build1" version. We use patchelf to manipulate
# certain shared libraries during the wheel building process (https://github.com/tensorflow/tensorflow/blob/master/tensorflow/tools/pip_package/build_pip_package.sh#L255-L262).
# When we use Patchelf versions <0.12, those shared libraries end up with a
# corrupted PT_NOTE program header. This was fixed in v0.12, see https://github.com/NixOS/patchelf/commit/43a33482b501b0f5ee9da312aabfca3806570cc9.
